Murray Gearboxes
Match the right gearbox by checking your Murray model number or the original part number first, then compare key details such as drive shaft position and pulley layout. Garden Tractor Spares supplies genuine and OEM gearbox parts for selected Murray machines, including complete assemblies for self-propelled mowers. If the drive cuts out despite a sound belt and cable, replacing the full unit is often the simpler and more cost-effective repair.

Frequently Asked Questions
Why does my mower drive keep cutting out?
If the drive jumps out while the belt and cable are both known to be working properly, the gearbox is a common cause. On a self-propelled mower, that symptom points you towards the complete gearbox assembly rather than the external controls.
Can a gearbox cause a grinding noise?
Yes, grinding from the drive on a self-propelled mower is one of the usual signs of gearbox failure. When that noise is coming from the transmission side, replacing the complete assembly is often the more economical repair than rebuilding it.
What must match on a replacement gearbox?
The key points are the drive shaft orientation and the pulley position. Compare both against your original unit before ordering so the new gearbox matches the mower correctly.
